It will be observed that tab control units such as I have disclosed in my prior patents and as shown at 14 in Fig. 4 may beused in 2, the printing device provided with openings 12, in which case the controller of the printing machine will be set to be operated by the tabs as described in my patents; or

elongated tabs 9 or 15 may be used in these printing devices with thel controller of the machine set accordingly. With the tabs 9 the heads of the tabs may be used rfor one set of classifications and the openings for .another set of classifications, the controller of the machine being set for one or the other classification, as may be desired. With the tabs 14 a variety of classifications can be obtained as described in my patents, and with the tabs 15 a still greater variety of classifications may be obtained because of the addition of the openings 12. It is customary in printing devices of the kind shown to provide the frame with a bead 17 at the top and with other devices 18 for receiving and holding an information card which is de-` tachably engaged therewith. I have shown these devices in the drawings and it will be readily understood that according to my present invention as herein discloseda card to be used in the frame as a part of the printing device must be provided with openings 'corresponding to those in the frame.

In Fig. 2 I have shown a card 19 provided with a series or row of openings 2O to register with the openings 12 in the frame of the printing device. The lower end of the stein of the tab control unit project-s over the opening in the frame and under the opening in the card to block both openings. With this invention it. is essential that the registered openings of the frame and the card in the classification selected for printing should be blocked so that the controller will be intercepted to effect an operation of the machine, and the arrangement of the lower end of the stem between the frame and the card is due to the keeper construction shown and described. It is obvious that the hole would -be blocked if the lower end of the stem were located at the back of the frame or at the front of the card instead of between ine andA ammo the frame and the card, and this can be v accomplished by reconstructing the kee rs.

I have not considered it necessary' to s ow the controller because that forms no part of the present invention and may be varied in construction and operation in many wa Ys. As an illustration of one form of controller which maybe used I ma mention that it can be in the form o f a pluralit of fingers ositioned in a .row to en ge t e openings in the printing device so t at as each printing device is brought into registration with the controller the fin ers will enter all of vthe unobstructed openings, but printing iinpressions will be taken only from those printing devices of a certain classification etermined by the index tab control units to which the machine has been set. The selected index tab control unit obstructs the finger of the controller according to the setting of the machine and this results in a 4printing impression from that printing device, and from every printing device having an index tab of the same kind and similarly disposed.

Bv using a tab with a specially shaped head in conjunction with an elongated stem, and the openings 12, 20, and controller means adapted for operation accordingly, a large classification may be provided for.

I am aware that changes in the form, construction and arrangement of the printing device herein shown and described may be made without departing from the spirit or sacrificing the advantages of the invention and I reserve the right to make all such changes as fairly fall within the scope of the following claims.

I claim:

1. A printing device having aseries of keepers extendingin a row across the device adjacent the upper edge thereof and openings below the keepers and aligned therewith, and an elongated index tab adapted to be detachably engaged with any keeper and to project belowthe keeper to obstruct the opening aligned therewith.l

2. A printing device having a keeper and a protuberance below the keeper and an opening below the protuberance, and an index tab detachably engaged with the keeper and having an opening'to engage the protuberance and projecting downward to obstruct the opening below the protuberance.

3. A printing device having a series of keepers extending in a row across the device adjacent the top thereof and a series of openings extending across the device below and parallel with the keepers, said openings being aligned with said keepers, and an elongated index tab adapted to be detachably engaged with any keeper and to'project below the keeper to obstruct the opening aligned therewith.

4. A printing device comprising a frame having a series of keepers extending in a card on the frame, and an elongated index row across` the frame adjacent the up er tab-adapted to be detachably engaged with ed e thereof-and a row of openin s be ow any keeper and to pro'ect below the keeper' 1 ancg adjacent the row of keepers an alignedV between 4the frame and the card to obstruct i therewlth, a card having a row of openin s the openings in the frame and card aligned to register with said row of openin s in t e with the keeper in which the tab is enga ed. frame, means. for removably hol 'ng the' Y' l JOSEPH S.
